Micromixers are considered an integral part in biomedical microfluidic applications because of important chemical and biological processes that require rapid and efficient mixing. In this work, flow regimes in throttle-T and square wave type micromixers are studied. The dependence of mixing efficiency on the geometry design is examined. Passive mixing methods with different flow rates at the inlets are studied experimentally using an imaging based technique. Moreover, a finite element model is used in order to study the mixing process of species in 500 µm and 400 µm - wide throttle and square wave microchannels, respectively. The results illustrated the effects of both flow rate and channel geometry on the mixing efficiency. Experimental studies at different flow rates are reported showing the same mixing tendency.
